- Log message:
- Change the exception handling logic:
Exception handler switches from exception mode to kernel mode(supervisor mode) before proceeding to
the exc_dispatch() C function. This assures that exception handling is re-entrant and
kernel would not get confused with different processor modes inside the kernel.
Also fixes a kernel panic during nested interrupts.
